MACHINE FOR MARKING CANS.

lle it known that l.A lli-:Nur GABRIEL G1- Nam, a citizen of the UnitedStates. residing at llonolulu7 county of llonolulu. Terre tory ofllawaii. have invented certain new and useful Iniprt'n'cnieuts inMachines for Marking Cans; and l do hereby declare the following to he afull. clear. and exact dcseriptinn of the invention, such as willenable. others skilled in the art to 4which it appertaiiis to make andyuse thesan'ie.

This invention relatesl to machines for niaiking cans or othercylindrical containers, either before or after filling. in order thatthe grade of the. contents of thc can may be known after sealing.

The objectof the invention is to produce a machine of this characterwhich shall be automatic, continuous and eieicnt in operation.

Another object is to niark the ean in two or three places on itsperiphery with siniilai type, so thabat least one niark `will alwaysappear to vieivand thus obviate the necessityof turning the can inorder-to observe the marking.

Another object is to adapt the niachine so that it can be quicklyaltered so as to niark the cans with a different niark or to niarkV cansof another size.

A further object is to provide means for marking cans which have beendented or are slightly out of round.

Machines have been made for marking either the top or bottom heads ofcans While conveyed by a link belt or wire rope. The ordinary1 method,however, is to stamp thc v,can by hand with a rocking motion of therubber or other type on the cylindrical portion of the can, usually iiia single placeonly. the marking indicating the contents of the pack.which afterward covered b v a suitable label. i'

Wvith lthe above mentioned objects in view. my invention consists in thenovel arrangement and construction of parts as .hcrwafter described and'claimed. refer- 'cnetA Aoeing had to the aeeouil'iaiivingdrawings.forming a part of this speciticatioin in which corresponding parts intheseveral figures arcdesignatcd by like charactersl ot reference. i

invention in a preferred foi-in. Fig. 2 is a similar view of a portionof the maehiiic shown in Fig. 1, illustrating more fully the means forimpressing the cans against the tvpe wheel. Fig. 3K is a front elevationof the machine. Fig. 4 is a rear view ot the' niaehine. Fig. 5 is asectional view on thel linc'A-B of Fig. 1. Fig. 6 is an enlarged view ofa portion of' thc face of the. type' wheel. Fig. 7 is alongitudinal"section through the center of Fig. G. Fig. 8 is atransverse section on the line C-D of Fig. (i. Fig. 9 is-a plan v"iew ofthe inking roller and the fork which supports the sanic.

Referring to the drawings. the body 1 of the machine -is preferably acasting and.70 provided with flanges 2 and 3' at its front,l andrearrespectively for supporting the machine upon transverse woodenbeams' 4. In the bearing 5 at the top of the hody'l is journaled theshaft G. `A sprocket wheel 7. and a pulley 8 are secured to the sliatt.(i on opposite sides of the bearing The lsprocket wheel 7 isprovided-witha sleeve or offset hub 9 on the side opposite to thehearing 5. A wheel 10 of'wood or other 80 suitable material visreniovabl)r secured on the sleeve or hub tl by nieansof-tl'ie washer 1land the nut .19. the. end of-the shaft t being threaded to receive-saidnut. A piiiA` 13 in the sprocket wheel 7 engages a hole 14 in the wheel10. so that this wheel is revolved with the shaft (l, Fig. 5. The wheel10 is'preferablv provided with two flat. traction rings l5 1G Of'rubberor other material. also with a plurality of rubber or other suitabletype 17- secured at: intervals between said rings to the cripheryof thiswheel. as shown. `The thickness of the type l? is greater than tliatofthe ti'aetioii'rings l5 lt. Figs. 7 and 8.

'.lwo flexible band-s 18 1t) -ot rubber belting or other suitablematerial are provided. their front. ends heilig attached to the lug Q0vof the body 1 and their rear ends to the lever ll respectively. Thelever ll is' fulerumed on the pin 22 secured in the bossv 23V of thebody' `1.v The. ends ot a tension spring 24 are connected to the leveril and to a hook in the bottom of the/hotly l, such that the bands 18 19are norn'iallv. tightened in a horizontal position. Fig. 1. The distancebetween the bands 18 19 and the wheel 10 is made less than the diameterbars are fastened to the angles 26 v27 respectively. Upper guard plates32 33 and a side bar 34 are attachedv to and supported by the frames 303,1, as shown.

The ink roller 35 is mounted to turn on the pin 36 in the fork 37, Fig.9. The fork 37 is provided with a hub 38 which is piv-y oted on the pin39 secured to the boss 4Q at the upper rear portion of the body 1,

Figs. 1 and 4. The ink roller 35 rolls on the distributing roller 41 andon 'the type 17 on the Wheel 10. The distributing roller 41 is attachedto the sleeve 42 of the sprocket 43 .which is mounted toturn on thepin'44 secured to the boss 45 of the body '1, Fig. 4. The sprockets 7and 43 are connected Aby a link -belt 46. The ink well 47 is secured bybolts 48 to the body 1, such that the rollerv 4l may revolve with aportion of said roller in ink in said well.

In operation the machine is driven in the direction as shown by arrowsby means of a belt applied to the pulley 8. The cans to be marked rolldown on the inclined angles 26 onto the flexible bands 18 19 and againstthe traction rings -15 16 on the wheel 10, which in revolving cause thecan to continue rolling rearward, the flexible bands 18 19 beingrdeflected from their normal horizont-al position, and against the actionof the spring 24, by the passage of the can or cans under the wheell 10,Fig. 2. During this passage under the wheel 10, however, the can hasrevolved about two-thirds of a revolution and has been successivelyimpressed by two or three of the type 17 which have previously beeninked by contact with the roller 35. The cans thus marked are pushedrearward by successive cans and are discharged from the machine byrolling down the inclined angles 27. The markings on the cans are notblurred by the adjacent cans, however, as the flanges of the headsprevent coutact of the bodies with one another, The flexible bands 18 19are placed far enough apart so as to clear the markings on the cans.`Although the can may be dented or lslightly out of round neverthelessthe flexible bands 18 19 force the can against the type 17 and producethe desired markings on the can in not less than two places. When "it isdesired'to change the mark, for example from the B grade as illustratedto some other grade or mark, the wheel 10 is easily replaced by. asimilar wheel with the desired type. "Vhen smaller cans are to bemarked, a Wheel 10 of a suitable larger diameter and a slightly smallervink roller 35 are employed, the change being easily and quickly made. f

The cans may be fed to the machine either by hand or by a suitableconveyer in a Well known manner.
